White House economic adviser Larry Kudlow said on Monday that the United States wants to end subsidies for electric cars and other items including renewable energy sources. "Asked about actions planned after General Motors announced U.S. plant closings and layoffs last week, Kudlow said he expected subsidies for buying electric cars will end in 2020 or 2021," reports Reuters. "Kudlow said the Trump administration will end other subsidies, including on 'renewables.'"

An anonymous reader quotes a report from Bloomberg: The world's largest retailer is rolling out 360 autonomous floor-scrubbing robots in some of its stores in the U.S. by the end of the January, it said in a joint statement with Brain Corp., which makes the machines. The autonomous janitors can clean floors on their own even when customers are around, according to the San Diego-based startup. Brain's robots are equipped with an array of sensors that let them gather and upload data.

Brain doesn't make its own hardware, focusing instead on developing software -- BrainOS -- that endows machines with autonomy in closed environments. At first, the machines were need to be operated by humans, who "teach" the layout of the space that needs cleaning. After that the robots can perform the task autonomously. The robots, which look like a cross between a miniature Zamboni and a motorized wheel chair, already scrub floors at airports in Seattle, San Diego, Boston and Miami, Brain Chief Executive Office Eugene Izhikevich said. Brain last month unveiled a smaller version of the machine developed jointly with SoftBank's robotics arm and aimed at the Japanese market.

DuckDuckGo, a privacy-focused search engine, offers a variety of useful features such as instant answers and bangs. The latter are particularly useful for people who want to use DuckDuckGo to search directly on other sites. Typing '!yt keyword', for instance, will do a direct search on YouTube, while '!w keyword' goes to Wikipedia. This library of bangs has been around for a long time and has grown to more than 10,000 over the years.

From a report: However, a few days ago, roughly 2,000 of these were removed. Interestingly, this included many bangs that link to torrent sites, such as The Pirate Bay, 1337x and RARBG. Similarly, bangs for OpenSubtitles, Sci-Hub and LibGen are gone too. Initially, it was unclear what had happened, but after people started asking questions on Reddit, DuckDuckGo staff explained that this was part of a larger cleanup operation. DuckDuckGo went through its bangs library and removed all non-working versions, as well as verbose ones that were not actively used. In addition, many pirate site bangs were deleted as these are no longer"permitted."

"Bangs had been neglected for some time, and there were tons of broken ones. As part of the bang clean-up, we also removed some that were pointing to primarily illegal content," DuckDuckGo staffer Tagawa explains. The search engine still indexes the sites in question but it feels that offering curated search shortcuts for these sites in their service might cause problems. "It may not seem like so at first blush, but it is very different legally if it is a bang vs. in the search results because the bangs are added to the product by us explicitly, and can be interpreted legally as an editorial decision that is actively facilitating that site and its content," the staff wrote.

An anonymous reader shares a report: Six former Facebook employees who left the company within the last two years told CNBC they've experienced a rise in contact from current company employees to inquire about opportunities or ask for job references. [...] The shift could be an early warning of recruiting and retention challenges for Facebook after a turbulent year. In 2018, the company has faced public questioning at multiple congressional hearings, scandals around third-party abuse of user data and public relations practicesand flat or declining user growth in key markets. It's also seen its stock drop nearly 40 percent from July. The stories from former employees are only anecdotal at this point, and there's no firm data showing a significant uptick in departures or employee dissatisfaction.

Though Blockchain has been touted as the answer to everything, a study of 43 solutions advanced in the international development sector has found exactly no evidence of success. From a report: Three practitioners including erstwhile blockchain enthusiast John Burg, a Fellow at the US Agency for International Development (USAID), looked at instances of the distributed crypto ledger being used in a wide range of situations by NGOs, contractors and agencies. But they drew a complete blank. "We found a proliferation of press releases, white papers, and persuasively written articles," Burg et al wrote. "However, we found no documentation or evidence of the results blockchain was purported to have achieved in these claims. We also did not find lessons learned or practical insights, as are available for other technologies in development."

Blockchain vendors were keen to puff the merits of the technology, but when the three asked for proof of success in the field, it all went very quiet. "We fared no better when we reached out directly to several blockchain firms, via email, phone, and in person. Not one was willing to share data on program results, MERL [monitoring, evaluation, research and learning] processes, or adaptive management for potential scale-up. Despite all the hype about how blockchain will bring unheralded transparency to processes and operations in low-trust environments, the industry is itself opaque." Burg was an enthusiastic advocate for blockchain until recently -- as he explained in this Medium post.

Tumblr, the underground social media site known for its pornographic content and tight-knit community, will be instituting a major change to its guidelines in a couple of weeks. The company said in a blog post today that it will permanently ban adult content from its platform on December 17th. The company flatly stated that "adult content will no longer be allowed here." The Verge reports: Banned content includes photos, videos, and GIFs of human genitalia, female-presenting nipples, and any media involving sex acts, including illustrations. The exceptions include nude classical statues and political protests that feature nudity. The new guidelines exclude text, so erotica remains permitted. Illustrations and art that feature nudity are still okay -- so long as sex acts aren't depicted -- and so are breastfeeding and after-birth photos.

After December 17th, any explicit posts will be flagged and deleted by algorithms. For now, Tumblr is emailing users who have posted adult content flagged by algorithms and notifying them that their content will soon be hidden from view. Posts with porn content will be set to private, which will prevent them from being reblogged or shared elsewhere in the Tumblr community. "Blogs that have been either self-flagged or flagged by us as 'explicit' per our old policy and before December 17, 2018 will still be overlaid with a content filter when viewing these blogs directly," the blog post reads. "While some of the content on these blogs may now be in violation of our policies and will be actioned accordingly, the blog owners may choose to post content that is within our policies in the future, so we'd like to provide that option..."

SpaceX notched its 19th launch of the year Monday, lofting 64 small spacecraft from 34 organizations into low Earth orbit. A Falcon 9 rocket lifted off from Vandenberg Air Force Base on California's central coast at about 10:34 a.m. local time. The customer was Spaceflight Industries, a Seattle-based company that organized the launch on behalf of several clients. From a report: The Spaceflight SSO-A: SmallSat Express mission includes 15 microsats and 49 cubesats from commercial and government entities, including universities, startups and a middle school, according to the SpaceX press kit. The payloads -- which vary from technology demonstrations and imaging satellites to educational-research endeavors -- are from 17 countries, including the U.S., Brazil, India and South Korea.

SpaceX said a series of six deployments would occur about 13 to 43 minutes after takeoff, then Spaceflight would command its own deployment sequences over a period of six hours. The Falcon 9's first stage has flown twice before: in May 2018 and again in August. SpaceX recovered it Monday on "Just Read the Instructions," a droneship in the Pacific Ocean. SpaceX also attempted to recover the rocket's fairing, which encloses the payload, with Mr. Steven, a boat designed to capture it in a massive net.

Skype is getting real-time captions and subtitles, and PowerPoint will have these features, too, next year. From a report: Ostensibly an accessibility feature (and launched on United Nations International Day of Persons with Disabilities), the new option means that Skype will be able to use voice recognition to show you the text of what is being said in a voice or video call. Microsoft will also bring the same feature to PowerPoint next year. Microsoft promises that live captions and subtitles are "optimized to be fast, continuous, and contextually updated as people speak", and in the current incarnation they will automatically scroll during a call. In a future update, however, it will be possible to manually scroll through subtitles and take advantage of additional viewing options.

Even as a furious debate broke out in China over gene-edited babies, some scientists in the US are also hoping to improve tomorrow's children. From a report: [...] Amid the condemnation, though, it was easy to lose track of what the key experts were saying. Technology to alter heredity is for real. It is improving very quickly, it has features that will make it safe, and much wider exploratory use to create children could be justified soon. That was the message delivered at a gene-editing summit in Hong Kong on Wednesday, by Harvard Medical School dean George Daley, just ahead of He's own dramatic appearance on the stage (see video starting at 1:15:30).

Astounding some listeners, the Harvard doctor and stem-cell researcher didn't condemn He but instead characterized the Chinese actions as a wrong turn on the right path (see video). "The fact that it is possible that the first instance of human germ-line editing came forward as a misstep should in no way lead us to stick our heads in the sand," Daley said. "It's time to ... start outlining what an actual pathway for clinical translation would be."

An anonymous reader shares a report: "We've launched our last satellite," John Donovan, CEO of AT&T Communications, said in a meeting with analysts on Nov. 29. The AT&T executive effectively declared the end of the satellite-TV era with that statement. AT&T owns DirecTV, the US's largest satellite company -- and second largest TV provider overall, behind Comcast. DirecTV will continue offering satellite-TV service -- it had nearly 20 million satellite video subscribers as of September, per company filings. But the company will focus on growing its online video business instead, Donovan said.

It has a new set-top box, where people can get the same TV service they'd get with satellite, through an internet-connected box they can install themselves. It expects that box to become a greater share of its new premium-TV service installations in the first half of 2019. It also sells cheaper, TV packages with fewer channels through its DirecTV Now and WatchTV streaming services, which work with many smart TVs and streaming media players like Roku and Amazon Fire TV devices. The practice of getting TV through satellite dishes propped up in backyards and perched on rooftops first took hold in the US in the last 1970s and early 1980s, after TV networks like HBO and Turner Broadcasting System started sending TV signals to cable providers via satellites. People in areas without cable or broadcast TV began putting up their own dishes to receive the TV signals, and that grew into a TV business of its own.

Trailrunner7 writes: Like real estate, we're not making any more IPv4 addresses. But instead of trying to colonize Mars or build cities under the sea, the Internet's architects developed a separate address scheme with an unfathomably large pool of addresses. IPv6 has an address space of 2^128, compared to IPv4's 2^32, and as the exhaustion of the IPv4 address space began to approach, registries started allocating IPv6 addresses and there now are billions of those addresses active at any given time. But no one really knows how many or where they are or what's behind them or how they're organized.

A pair of researchers decided to tackle the problem and developed a suite of tools that can find active IPv6 addresses both in the global address space and in smaller, targeted networks. Known as ipv666, the open source tool set can scan for live IPv6 hosts using a statistical model that the researchers built. The researchers, Chris Grayson and Marc Newlin, faced a number of challenges as they went about developing the ipv666 tools, including getting a large IPv6 address list, which they accumulated from several publicly available data sets. They then began the painful process of building the statistical model to predict other IPv6 addresses based on their existing list.

That may seem weird, but IPv6 addresses are nothing at all like their older cousins and come in a bizarre format that doesn't lend itself to simple analysis or prediction. Grayson and Newlin wanted to find as many live addresses as possible and ultimately try to figure out what the security differences are between devices on IPv4 and those on IPv6.

Apple plans to hold off until at least 2020 before offering an iPhone that can connect to the next generation of high-speed phone services coming next year, Bloomberg reported Monday. From the report: The delay may make it easier for rivals like Samsung Electronics to win over consumers to phones that connect to 5G networks, which will provide a leap forward in mobile data speeds when they are introduced in 2019. As with 3G and 4G, the two previous generations of mobile technology, Apple will wait as long as a year after the initial deployment of the new networks before its main product gets the capability to access them, said the people, who asked not to be identified discussing the company's plans.

Apple's previous calculations -- proven correct -- were that the new networks and the first versions of rival smartphones would come with problems such as spotty coverage, making consumers less compelled to immediately make the jump. This time, 5G boosters argue the switch is a much bigger speed upgrade, making Apple's decision to wait riskier. The networks will open the floodgates to new types of mobile computing, 5G advocates say.

Are students being short-changed by their $60,000 degree courses? And does a university education in 2018 represent good value for money? A slew of recent government and think-tank reports aim to tackle these questions. And the answers they give are not encouraging. From a report: The Public Accounts Committee announced this month that the value of the UK's student-loan system is falling. Last year, the government sold a tranche of the student-loan book at a major loss. The portfolio had a face value of $4.4 billion, but was sold for just $2.1 billion: a return of 48p in the pound, according to the public-spending watchdog. Clearly, the current method of funding higher education represents a bad deal for the taxpayer.

But do universities offer good value for students? Not when you consider the fact less than half the money that students pay in tuition fees is actually spent on teaching, according to a report by the Higher Education Policy Institute. The rest of the money from tuition fees goes into other services and parts of the administration. These include admissions procedures, marketing, vice-chancellor pay and programmes to boost access for poorer students, as well as therapeutic services like mental-health provision and exam-stress counselling.

Universities today have far too much bureaucracy, fat-cat VC's salaries are far too high, and a great deal of what administrators spend money on is a hindrance to education. University bureaucracy is often at the forefront of coddling students, encouraging them to see exams and hard work as threats to their mental health. It is troubling to see that students are not only plunging themselves into debt at such a young age, but also that much of that debt does not go towards their actual education.

The first clinical trial is underway to test a new male contraceptive that could be a game changer for preventing pregnancy. From a report: "(It's) a combination of two horomones: Progestin, which is the typical horomone that is found in female contraceptive pills, which they put in there to suppress sperm production, to trick the body, and testosterone, which is the male sex horomone so that there's normal circulating levels of testosterone that men don't lose their libido or sexual function or have any changes in mood," said CBS News medical contributor Dr. Tara Narula.

The National Institutes of Health is enrolling about 420 couples to use an experimental gel that has been in development for more than 10 years. If proven effective, it would be the first hormonal birth control for men. The gel is applied to the back and shoulders. Researchers found that testosterone, once absorbed through the skin, stays in the system longer than testosterone taken in pill form does. Male volunteers will use the gel every day for four to 12 weeks.

Valve officially announced this week the arrival of Steam China in Shanghai. But Chinese gamers are telling the PC gaming platform to "get lost!" From a report: One of the most upvoted comments wrote, "Steam China get out of China." It's important to point out that gamers are directing their anger at Steam China, not Steam. In fact, Chinese gamers love Steam... the global version of it, anyway. There are an estimated 30 million Chinese users playing games on the platform -- games which otherwise aren't officially available in China.

But that's exactly why they fear the launch of Steam China, which is a joint venture between Valve and Chinese company Perfect World. Gamers worry that not only will Steam China be a heavily censored platform with a much smaller lineup of titles; worse yet, it might also be the trigger for the government to ban the global version of Steam.
